A transparent thin film electroluminescent display device includes a first transparent thin film electroluminescent display having a substrate and a first active layer capable of emitting a spectrum of light in a wavelength of visible light. The transparent thin film electroluminescent display device further includes a second transparent thin film electroluminescent display having a substrate and a second active layer, the first and second transparent thin film electroluminescent displays being arranged in a superposed manner such that the first and second active layers are spaced apart from each other for forming the transparent thin film electroluminescent display device with a superposed structure.

An optical targeting device comprised of a support body, an imaging waveguide joined to and in a position relative to the support body, and a light source mounted on the support body. The imaging waveguide is comprised of an input diffractive optic, and an output diffractive optic. The light source is located to direct a targeting light beam to the input diffractive optic of the imaging waveguide. In operation of the optical targeting device, the imaging waveguide simultaneously transmits incoming light from a scene viewable by a user of the device through the light transmissive body, and propagates the targeting light beam from the input diffractive optic laterally through the light transmissive body and directs the targeting light beam outwardly from the output diffractive optic, thereby rendering the targeting light beam as a point of light superimposed within the scene viewable by the user.

The present invention is an optical assembly featuring an architecture which allows adjustment of both objective lenses and the electronic sensing assemblies in the optical assembly. Electrical connections in the housings of the various subassemblies allow focusing adjustment by rotational and/or translational movement for increased adjustability.

The disclosed optical beam expander may include (1) a monolithic structure including (a) a first nonplanar mirror that receives a first collimated optical beam having a first width and reflects the first collimated optical beam to generate a noncollimated optical beam and (b) a second nonplanar mirror that receives a diverging optical beam and reflects the diverging optical beam to generate a second collimated optical beam having a second width greater than the first width, where the first nonplanar mirror and the second nonplanar mirror are fixed in orientation and position relative to each other and (2) a planar mirror that reflects the noncollimated optical beam from the first nonplanar mirror to provide the diverging optical beam to the second nonplanar mirror. Various other devices, systems, and methods are also disclosed.

Systems and methods for a weapon mountable tactical heads-up display (HUD) are provided. The HUD may include a 9 degrees of freedom (9DOF) sensor, a target library, and a target finder visualization. The target library may store respective ballistic information for each target of a plurality of targets. The respective ballistic information may include a target vector for each target of the plurality of targets. The target vector may be calculated based on data received from the 9DOF sensor. The target finder visualization may allow a shooter to locate a selected target of the plurality of targets. The target finder visualization may be based on the target vector.

It comprises optical assemblies that focus light onto individual first optical fibers which are combined together in a final single optical fiber, collecting a considerable amount of light from a target, to feed an instrument such as a spectrograph. The first optical fibers are kept centred on the target through image devices that also provide images, and these images can be combined to give rise to a high-quality image of the field surrounding the target. The final effective aperture of the device is scalable, using different numbers of optical assemblies and depending on their diameters.

A firearm sighting optic that can have the lenses easily and quickly replaced by the user is disclosed. This sighting optics allows the lens to be inserted from the bottom of a red dot sighting unit and then be secured by set screws. The firearm sighting optic includes a base and a hood. The lens is removably retained with the firearm sighting optic by user removable fasteners securing the hood to the base. The lens is housed in a hood that makes sliding the replacement lens into the unit much easier. The hood and base include an interconnecting protrusion and recess for reliable alignment of the lens within the hood and the base.
